Actually, LJ sends blogpings (messages that say, "hey! scan my web site! I've changed recently!") to various "blogping collection sites". Blogsearch.google.com and others connect to the collection sites and query for new entries. They then use those entries to crawl those sites, and add the updated pages to the index.
The search system references the index.
A blogping can result in something being searchable within minutes, sometimes seconds.
All major blogging software packages support blogpings now. It's pretty cool.
